Running against time today, so this is going to be a quick post.
I just wanted to refer you to this post, which is an excellent summary of last night's Question Time, this is being talked of in manyplaces.

In addition, there's a post from a couple of days ago to help people who are confused about how to vote, though some conclusions are dodgy here. In my constituency it is a LD/Tory race, so if all you want to do is diminish labour, then one should vote one's conscience!
